The aim of Surgery is to remove the DCIS and the tissue around it in an operation. Surgery can remove the milk ducts containing the DCIS (a lumpectomy) or the whole breast containing the DCIS (a mastectomy). Depending on the findings at surgery, this may be followed by radiation therapy.
Surgery may be outpatient or require a stay of several days in the hospital. Recovery may take days or weeks. Your time in the hospital and recovering will depend on the type of operation, any side-effects you have, and whether you have a breast reconstruction. You will have checks during recovery, a check-up with a clinician every six months, and annual mammograms.
